(b) allowing trading in water entitlements, to achieve environmental outcomes.

(3) Subsection (2) does not limit the matters the chief executive may consider. 38 Managing low flows (1) The purpose of the rules for managing low flows is to maximise environmental benefits and the reliability of supply of water for stock and domestic purposes. (2) To achieve the purpose, the rules must ensure that, if an inflow occurs to Beardmore Dam and more than 12 months has passed since a flow through event, the likelihood of a flow through event is maximised by—

(a) releasing water that has been stored for stock and domestic purposes; and

(b) if the release mentioned in paragraph (a) is not likely to result in a flow through event, both—

(i) if the threshold for water harvesting has been reached—

(A) reducing water harvesting to 90% for the period of the flow event up to a maximum period of 5 days; and

(B) reducing by up to 10% the volume of water that could have been taken by weirs below the Jack Taylor weir; and

(ii) managing bifurcation weirs; and

(c) if the actions mentioned in both paragraphs (a) and (b) are not likely to result in a flow through event—releasing up to 10% of the inflow that would usually be stored for use under water allocations in the St George Water Supply Scheme.

(3) In deciding the rules, the chief executive—

(a) must consider making use of privately-owned facilities for the storage and subsequent release of water; and

(b) must ensure that—

(i) water made available under a rule mentioned in subsection (2) is taken only for stock or domestic purposes; and

(ii) during subsequent flow events after the rules mentioned in subsection (2) have been followed, priority is given to replacing water released under a rule mentioned in subsection (2) (c).

39 Managing medium flow events (1) The purpose of the rules for managing medium flow events is to provide for improved flows, especially low and medium flows, that mimic the natural variability of the river system and floodplains. (2) To achieve the purpose, the rules must ensure that, if a flow event happens in either of the following circumstances, water harvesting must be reduced to 90% for the period of the flow event up to a maximum period of 5 days—

(a) more than 2 years has passed since a flow event with a peak of at least 60000ML a day at Jack Taylor weir;

(b) more than 3 years has passed since a flow event with a peak of at least 100000ML a day at Jack Taylor weir.

40 Managing Narran Lakes filling flow events (1) The purpose of the rules for managing Narran Lakes filling flow events is to improve water availability for bird-breeding in the Narran Lakes Ramsar site. (2) The rules must ensure that, if a flow event of a volume sufficient to fill the Narran Lakes Ramsar site under the pre-development flow pattern occurs during the winter bird-breeding months, water harvesting must be reduced to 90% for the period of the flow event up to a maximum period of 10 days. (3) The rules must also ensure that, if both of the following happen, water harvesting must be reduced to 90% for the period of the flow event up to a maximum period of 10 days—

(a) the Narran Lakes Ramsar site has filled during the winter bird-breeding months;

(b) within 4 months after the site has filled, a flow event that would re-fill the site under the pre-development flow pattern occurs.

41 Application of rules mentioned in ss 38–40 If more than 1 of the rules mentioned in sections 38, 39 and 40 apply in particular circumstances, the maximum period for which water harvesting may be reduced is the greater of the periods mentioned in the rules that apply. 42 Compensation rules for flow event management (1) If the taking of unsupplemented water has been reduced because of flow event management, the resource operations plan must contain rules that allow holders of water entitlements to take unsupplemented water to take additional water to compensate them for the reduction. (2) In deciding the rules, the chief executive must—

(a) consider options for water entitlement holders to take water at times of high water availability; and

(b) ensure any increase in the taking of water under the rules does not adversely affect the achievement of the purposes for flow event management; and

(c) ensure any increase in the taking of water under the rules does not adversely affect the ability of other entitlement holders to take water under their entitlements; and

(d) ensure the additional water is taken as soon as practicable and not carried over.

Subdivision 3 Other rules for the Lower Balonne 43 Water sharing rules for the St George Water Supply Scheme (1) The resource operations plan must contain water sharing rules for water allocations managed under the St George Water Supply Scheme. (2) The rules must state—

(a) the extent to which the difference between a water allocation holder’s nominal volume and the volume of water taken in a water year may be taken in the following year (the carry over volume); and

(b) the extent to which a water allocation holder may take more than the holder’s available allocation in a water year by drawing on the holder’s available allocation for the following year (the forward draw volume).

(3) In deciding the rules, the chief executive must ensure—

(a) the total of carry over volumes for water allocations in the St George Water Supply Scheme is not more than 20% of the total of the nominal volumes for allocations managed under the scheme in the water year; and

(b) the total of forward draw volumes for water allocations in the St George Water Supply Scheme is not more than 10% of the total of the nominal volumes for allocations managed under the scheme in the water year; and

(c) the taking of forward draw volumes does not adversely affect the reliability of supply of other supplemented water allocations; and

(d) if forward draw volumes are taken in a water year—
